Teaching How to Generate Wildcard SSL Certificates for your LBaaS

Security is super important, but also annoying. From a backend developer mindset, all I want is to build great services exposed as APIs that the world can consume with ease. The problem is that in most cases, consumption of my endpoints will be blocked by browsers and other tools/client unless they are exposed as HTTPS with valid SSL certificates.

In this blog, I am going to show you how to use Let’s Encrypt to create your own “Wildcard SSL Certificate” for your existing domain, for example: *.mydomain.com – Then I am going to show you how to assign this certificate to your Oracle LBaaS Listener endpoint.

For these steps, I am using an Ubuntu VM. Feel free to adapt the instructions if you are using a different OS.

I am extremely passionate about people, technology and the most effective ways to connect the two by sharing my knowledge and experience.
Working collaboratively with customers and partners inspires and excites me, especially when the outcome is noticeable valuable to a business and results in true innovation. I enjoy learning and teaching, as I recognise that this is a critical aspect of remaining at the forefront of technology in the modern era.
Over the past 10+ years, I have developed and defined solutions that are reliable, secure and scalable, working closely with a diverse range of stakeholders. I enjoy leading engagements and am very active in the technical communities – both internal and external. I have stood out as a noticeable mentor running technology events across major cities in Australia and New Zealand, including various technology areas such as, Enterprise Integrations, API Management, Cloud Integration, IaaS and PaaS adoption, DevOps, Continuous Integration, Continuous Automation among others.
In recent years, I have shaped my role and directed my capabilities towards educating and architecting benefits for customers using Oracle and AWS Cloud technologies. I get especially excited when I am able to position both as a way to exceed my customers’ expectations.
I hold a bachelor degree in Computer Science and certifications in Oracle and AWS Solutions Architecture.
